Found this routing while looking for a good end of year run to maintain Diamond on Delta. Four flights in Apex suites -- two on the 787-9, two on the top deck of a 747. This far exceeds the experience you'll get on China Eastern for the same money.
The YYZ-ICN-KUL-ICN-YYZ routing will earn 28,412 MQM and 7,578 MQD, in addition to the nearly 40k redeemable miles you'd earn if you're already Diamond on Delta.
Timing of the flights are good too -- very easy to position to YYZ from major east coast cities.
